There was going to be a sequel to Skies of Arcadia called Skies of Arcadia 2 for the GameCube and PS2, as confirmed by interviews with developers from the original team. The game never got beyond the planning phase, however, and it was ultimately never created.

In the Japanese SEGA Dreamcast version of Skies of Arcadia, Gilder has a victory pose in which he smokes a cigar. This was taken out of the game in other releases and changed to the victory pose of his parrot perched on his shoulder.
